The traditional vehicle-mounted power supply method is divided into two types, one is to adopt the inversion power supply of a storage battery, the power supply is high in quality, but the storage battery cannot be replaced in the working process, and the long-time or long-distance experiment requirement cannot be met; a small-sized gasoline (diesel) generator is adopted to provide alternating current, and can be used for oiling and storing electricity, but the working noise is large, high-quality alternating current cannot be provided, and the high-quality requirements of some precise experimental equipment on a power supply cannot be met. Therefore, the inverter power supply device for the test vehicle, which can output 220V50Hz high-quality sine wave alternating current, can replace a storage battery without cutting off the alternating current output, has small volume and low cost, and has important significance.
An Inverter (Inverter) is a power conversion device that converts direct current power (battery, storage battery pack) into alternating current (typically 220V50Hz sine wave).

The device is mainly used for providing stable and uninterrupted power supply for computers, precision experimental equipment or other power electronic equipment such as electromagnetic valves, pressure transmitters and the like. When the mains supply is normally input, the UPS stabilizes the mains supply and supplies the power to a load for use, and the UPS is an alternating current type electric stabilizer and charges an internal battery; when the commercial power is interrupted (accident power failure), the UPS immediately supplies 220V alternating current to the load by using an inverter switching method, so that the load keeps normal work and soft and hardware of the load are protected from damage. UPS's typically provide protection against either over-voltage or under-voltage.
The invention has the key points that the change-over switch, the inverter and the UPS are combined, the change-over switch is controlled to select the storage battery to supply energy, the direct current output by the storage battery is converted into the 220V50Hz sine wave alternating current by the inverter, the voltage, the frequency and the waveform of the alternating current are stably output by the UPS, meanwhile, the short-time power output is ensured under emergency conditions, and finally, the inverter power supply device for the test vehicle, which can output 220V50Hz high-quality sine wave alternating current, can replace the storage battery without cutting off the alternating current output, can provide short-time power output under emergency conditions, and has small volume and low cost, is realized.
